Good evening folks. I am way out of my depth here but looking to learn & any help would be appreciated please.
The system I would like help with is for automotive use on a low power consumption basis.
A feed would be generated from a switch (12v), and I would like to make a circuit that powers a motor for 3 to 4 seconds and leaves the motor stationary once the time has passed. When the switch has opened again, I would like the circuit to reverse the cycle and return the motor to the previous position.
How difficult is this likely to be to make and or cost?
The more basic, the better for me.
Finally, I would like to thank anybody who reads this, and more for any help you folks are able to offer in my quest.
Thanks in advance John.
